This combination offers ride height adjustment and 12-position valving adjustment for performance not found in other kits. This coil over kit reduces front end weight by 10lbs and is a direct bolt in application.

  • (2) Specially designed conical springs

Spanner Wrench- Spanner wrench tool is used to adjust vehicle height while shock stays mounted. This wrench is needed to make height adjustments.

Thrust Bearing Kit- Thrust bearing kit is designed to be placed between the spring and the spring seat attached to the shock. This makes for easier adjustments since the spring seat is rotating on a bearing. This kit is recommended for easy adjustments but is not needed to complete the installation.
